DEHOUNTABLE RIM WIX'IH DETACHBLE RING- Appunti@ inea Auguri 2o, 1924.semi No. 782:,023.

To `all Awhom t 'may concern:

Beit known thatv I, JAMEs H. VAGEN- Hons'r, e citizenof the UnitedStates, residi Jackson, in thefeounty of Jackson er. idiote of Michi enhave invented. a certain new and use ul, lnprovement in De mountabieRims-with Detachable Rings, o1' which the foilowingis a full, clear, andexactV description, reference being had to the accompanyingl drawings.

This invention relates generally to alito mobile wheels and moreparticularly to thel novel'constrnction ofthe fixed rim of the Wheei`body andthe demountable tire carry ing rim usable in connectiontherewith.

One object of the invention is to provide a deinonntehie tire carryingrim having e detec-treble side ring,l said rim having clampingr lugspermanently attached thereto et definite points, the front leg of thefixed rim being recessed or depressed to receive the .clamping lugs anda portion of the demount- .this section b'einp; taken at o point betweentwo of the clamping lugs: Fig. 2 isa sin iler sectional view tekenthrough one of the clamping lugs, the bolt and nut being shown inelevation; Fig. is e side view showing e portion of the outer leg of thefixed rim.

in carrying ont my invention, I empioy :i sheet metal fixed rimcomprising e base portion rear leg B and front leg C, the 'front leg`being formed with n, rearwardly projecting; inclined flange D whichextends entirely around the fixed rim except at cer- {wiin designatedpoints where' the front leg vis pressed rearwardly eslzshown et E and inpressing; this leg rearwardly at these points ibe flange j) is caused todisappear as most clearly shown in Figs. 2 and 3. At the points wherethe 'front leg ot' the fixed rim is recessed or pressed renrwardl I provide boit openings F through w ich pass the axial bolts G, the rear.ends being preferably formed with square shoulders fitting in squareopenings in the rear-leg of the fixed rim. H indicates the demountabletire carrying rim which is formed at the' vreni side with a tireengaging iange I and at the front side is shaped to provide e groove Kadapted to receive the detachable ange ring L. The grooved side of thedemotintable rim -is adapted te contact with the ,iange D of the frontleg of the xed rim. The front leg of the. fixed rim is of less widththan the rear leg in order to permit 'the demountable rim to beeaeilypiaced nponend removed from the fixed rim. (Stamping lugs M arepermanently :attached to the grooved side of the demonnteble rino. etdefinite points, the grooved' portion of the rim being :iperturcd toreceive the rivet lugs M which are projected through the openings endheaded down as indicated nt M2 sind innsn much as the base of thedetachable eng'e ring does not extend into the bottom of the groovethere will be ample space 'for producing ai considerable head on therivet. The clamping lug is 'formed with a considerable shoulder M3 whichis upon each side of the rivet lug M and contacts with e fiattenedportion of the grooved side of the rim bese es'most clearly shown inFig. 2.

This shouldered portion oi' the clamping; lng gives a. firm bearing ofthe Ciampino; ing; upon the rim bese and provides ampie .been ing forboth the rim :ind clamping iugdnr ing' the riveting' operation so thato. eomparntively perfect union between the chimp mg' lng end the groovodside of the rim bese cnn be obtained. vThe reni' portion of theclamping; lng in so shaped ns to lit within the recessed; or innrcssedportion oi the front ieg'oi'l the feliy and et the point where theclamping iur; is attached, the groot/ed side oi' the demonntebie rim ispressed rearm Werdiy as most clearly shown in Fig. E2 whichinwerdlypressed portion eiso fits into the recess in the front ieg ofthe eily sind this manner the driving;- eonneotion is estnbisbed betweenthe fixed end demounteble rims and strains relieved from the bolt andalso the clamping lug.

In applying the demonl'itnble riln to the fixed rim it will of course heunderstood that the npertured lugs fit upon the projecting ends oi4 thebolts G and nuts N are screw vupon said rojectingends, these nuts being'formed Wit tapered ende which iit into the' counterbored bolt openingsin the clamping l grooved side of the rim base, rocking of the clampinglugs with reference to the dcmountable rim is prarticaliv avoided.

It will thus be `seen that I provide a very durable and efficientconstruction of deniountable tire carrying rim capable of use inconnection with a channeled sheet metal k'fixed rim and capable othaving a substantial driving connection therewith.

Having thus described my invention, what I claim is:-

l. In a Wheel body, the combination with a fixed rim the front leg ofwhich is flanged, said front leg being recessed at definite points andbolt openings produced in said rim at said recessed points, of boltspassing through the front leg of the fixed riiii, a deinountable tirecarrying rim having a ring recci ving groove at the front side, clampinglugs attached to the groove side of 'the rim at definite points, saidclamping lugs bey ing apertured to receiver the rim bolts, nuts upon theends of said bolts, portions of said clamping lugs and portions of' thegrooved side of the rim base to which the clamping lugs areattachedfitting into the recessed portions of the fixed rim.

2. The combination' with a fixed rim having` a flanged -front leg, saidflanged front leg being irczszscd at definite points and bolt openingsioduced in said front leg at said recessed nein of a deuiount able tirecarry- ;j a ring receiviugi groove in side thereof. clamping lugs at-:hed to the tue rim, saic. 'liortions `injecting through the'groovedportion et? the. rim base, said' clamping lugs having shoulders adjacentsaid rivet portions, said shouldered portion contacting with the innerface of' the grooved side of the dinnountable rim, bolts passing throughthe aperture-:l ieg ol' the fixed rim and through the clamping llugsattached to` the deniountable rim, nuts upon said bolts, portions ofsaid clamping lugs fitting .into the recessed portions of the front legof the fixed rim.
